For a line to be perpendicular, their slopes must be reciprocals. So, a line perpendicular to y=2x+8 is y= -1/2 x +8
Answer:
1/3
Step-by-step explanation:
3×x=1
x= 1/3
The input of each of these functions is always an angle, and as you learned in the previous sections, these angles can take on any real number value. Therefore the sine and cosine function have the same domain, the set of all real numbers, \begin{align*}R\end{align*}
This linear equation is written in point-slope form, meaning that the constant outside of the (x - 4) is the slope: -2.
Perpendicular lines' slopes are oppositely negated, so -2 turns into positive 1/2.
So, the slope is 1/2.
Well see here that it practically gives us the answer. The submarine rises 4.3 meter each minute of the first 15 minutes. Multiplying these two given numbers you get 64.5 . Great we're halfway through. Now onto the second equation. 5.2 times 12 . easy right? The answer round to 62.4 . Now all that's left to do is add the two together. After the 27 minutes the submarine should be at an elevation of 126.9 feet. rounding to 127 if you teacher requires you to round the numbers.
